[PATCH V6 0/6] kdumpctl: force rebuild when dump target is modified
by Pratyush Anand
Kexec-tools should be able to recognize if a dump target is reformatted, or
dump path mounts another device.
Changes since v5:
- Couple of spellcheck in comments
- name convert for $_target while discovering $_fstype
- an extra "grep $_id" when dracut argument has "by-uuid"
- No need to check if ssh/nfs/raw target is specified. We will fix such
cases latter by introducing separate checks for them
Changes since v4:
- patch 4/5 is a new change
- patch 4/4 of V3 is now 4/5. There has been many modifications in this
patch. It includes feedback from Baoquan and Xunlei. Have also done some
modification to recognize changes related to minix and NFS filesystem as
well. Infact, whole structure of function is_fs_uuid_changed() has been
modified. Now it has been renamed as is_dump_fs_modified() to suit it
better. Although I have tested it rigorously, but still a careful review
of is_dump_fs_modified() will be helpful.
Changes since v3:
- "$ret" unquoted
- No message for "$system_modified" != "0"
- image_time is now global
- is_dump_target_modified has been renamed as is_fs_uuid_changed
Changes since v2:
-- now is_system_modified returns 2 in case of invalid modification, 1 in
case of valid modification and 0 in case of no modification.
-- file modification check has been moved to is_system_modified now
-- variables have been put under "" in if condition check
Changes since v1:
-- Local variable is defined in shell function now
-- raw target does not take persistent names "by-uuid" now
-- dracut arguments grep is more robust
-- When no UUID then warn and return
*** BLURB HERE ***
Pratyush Anand (6):
kdumpctl: Do not rebuild initramfs when $KDUMP_BOOTDIR is read only
mkdumprd: do not lookup in by-uuid dirs for raw device's persistent
name
kdumpctl: force rebuild in case of dynamic system modification
kdumpctl: Move file modification check logic in is_system_modified()
mkdumprd: move to_dev_name() to kdump-lib.sh
kdumpctl: force rebuild in case of file system is modified
